To all whom it may concern:

Be it known that we, CARL SoHL-ossER and SAMUEL KNAUss, citizens of the German Empire, residing atStuttgart, Kingdom of Wi'irtemberg, Germany, have invented new and useful Improvements in and connected with Means for Illuminating Advertisements and the Like; and we do hereby declare the following to be afull, clear, and: exact description of the same; I

This invention relates to an apparatus, for advertising purposes, which allows of the extinguishing and re-lighting, in brief" uniform succession, with marked alternate intervals of darkness, of the gaslampsilluminating a shop window, an advertising transparency, orthe like.

As compared with other devices for using gas lamps for advertising purposes ,the pres. ent invention is characterized by its great simplicity which'in spite of the use of the same apparatus by an alteration in the communication with the outlet apertures, allows of the illuminating being effected with a dif' ferent number of jets. The admissionof the gas to the separatebranch pipes according to the present invention is regulated by a holder or socket rovided with a suitable number of slots whic rotates continuously in the gas distributing chamber and always exposes, at equal intervals of time, one aperture ofthe gas outlets,- and closes the others. This regulating socket is operated by a clockwork and suitable gearing, the arbor of which passing through a kind of stufling box forms the connection ofthe distributing chamber with the clockwork.

In the apparatus according to the present invention not only may the jets be separately and alternately ignited and extinguished but also a number of variations are possible, thus, for instance, all the jets may be ar ranged for permanent burning and for alternate burning and extinguishing, or the jets may also be caused to burn in pairs or in groups.

One example of utilization of the object of the present invention, isshown in the accompanying drawings, in which t Figure 1 is an elevation of the device in partial axial vertical section, and in combination with a spring mechanism serving as a driving gear; Fig. 2 is an enlarged view, in axial vertical section, of the device; Fig. 3 is a partial horizontal section through Fig. 1,

and showing the several gas-"distributing pipes. Figs. 4, 5, 6and 7, illustrate the deslots g g g 9 each ofv which connects the,

interior of the distributing body with the pipes 6 ,6 12 andb. I Vithin said socket 6, there is another rotatable socket f, having slots 7L therein, and so disposed that but one of said slots registers or communicates with one of the slots g g g 9 at any given moment.v A clockwork is provided for operating socket and comprises a transmission arbor, 7c, having a catch pin Z which engages behind a catch or fork m. The latter is mounted on a s indie n the head 0 of which is tightly packed in a groove or recess, filled with grease or the like, in the bottom part (1 which closes the gas distributing body a from beneath. The head 0 has a recess into which fits a projection of the socketf, which latter is secured to the head 0, by means of a pin which passes through said head and throug a slot 9 of the projection. In order to insure a sure gas-tight closing, the bottom 01 is formed as a stufiing box'and has a grease box 8, the grease of which may be forced by means of a regulatable nut r as required, with more or less pressure, against the spindle 'n. VJ hen the socketf is rotated, the exits b b 6 andlf, and theslots g g, g and 9 are alternately exposed and closed at equal intervals. If, in the use of the device, only one small jet (Fig. 4) is to be ignited and extinguished alternately, for instance at equal periods alternating with marked periods of darkness, all the outlets or conduits a a a and a (which may be said to correspond to the pipes 6 b b 6 lead from the slots g g 9 g and are connected with a single lamp t which may be one of a series. Thus, as the socket f is revolved, the successive slots h thereof are brought into register successively with but one of the slots g g g g and the lam t is repeatedly lighted and extinguis ed. The same device may be successfully employed for successively and alternatingly lighting and extinguishing two lamps t and t (Fig. 5), with marked periods of darkness between the lighting of either. For this purpose, alternate conduits are both connected with the same lamp,thus conduits a and u are connected with lamp t and conduits a and u are connected with lamp t and each lamp will be ignited whenever, during the rotation of the socket f, either conduit of the pair is supplied with gas, and will be extinguished whenever both conduits of said pair are shut off, by socket f, from the distributing body. When connected as shown in Fig. 5, the lamp t is first ignited, is then extinguished, the lamp t is next ignited, and then extinguished, and this cycle nected, by a single conduit u, with the dis tributing device, lamp t may be connected, by a single conduit u with said distributing device, and the lamp i may be connected, by two separate conduits, with the distributing device. When thus connected, the lamp t is first ignited, and then extinguished, the lamp t is next ignited and then extinguished, the lamp i is next ignited and then extinguished, and the lamp t is again lighted and then extinguished; and this cycleincluding a lighting of lamp t after a lighting of either lamp 2? or F, and a marked interval of darkness after lighting of any lampis repeated as often as desired.

For the successive lighting, singly, of lamps of a series-with marked intervals of darknessthe distributing device may be used as shown in Fig. 6, which illustrates means for lighting first lamp t extinguishing the same, then lighting lamp t and extinguishing the same, then lighting lamp t and extinguishing the same, and then ighting lamp t and extinguishing the samerepeat ing this cycle (including lighting only one lamp at any time, with a marked interval of darkness between every lighting) as often as desired. For the ignition of any of the lamps (t t t, If) any suitable means such as a pilot burnermay be used.

What I claim is 1. The improvement in apparatus for illuminating advertisements and the like, comprising a gas-distributing chamber, distributing pipes leading therefrom, and a fixed perforated socket for connecting each of the distributing pipes with said chamber, in combination with a rotatable distributing socket having openings disposed to successively register with one only at a time of the perforations of the iixed socket and to successively close communication with all such perforations, and with means for rotating said distributing socket.

2. The improvement in apparatus for illuminating advertisements and the like, con'iprising a gas-distributing chamber, distributing pipes leading therefrom and a tubnlar socket lixed within said chamber and provided with perforations one for each distributing pipe, in combination with a rotatable tubular distributing socket also within said chamber and having openings disposed to successively register v.ith one only at a time of the perforations of the first-named socket and to successively close eoinnninication with all such perforations, one of said sockets closely surrounding the other.

3. The improvement in apparatus for illuminating advertisements and the like, comprising a gas-distributing chamber, distributing pipes leading therefrom, and means for establishing communication between said chamber and said pipes successively one only at a time and at equal intervals of time and for successively cutting on such communication with all pipes other than the one desired.

In testimony whereof, we have signed our names to this specification in the presence of two subscribing witnesses.
